The comprehensive use of models in design has created a set of challenges beyond that of supporting one isolated design task. In particular, the need to combine, couple, and integrate models at different levels of abstraction and in different formalisms is posing a set of specific problems that the field of Computer Automated Multi-Paradigm Modeling (CAMPaM) is aiming to address. This paper summarizes the results of the 2nd Workshop on Multi-Paradigm Modeling: Concepts and Tools
